- Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
- Male homosexuality Male homosexuality,male homosexuality
- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- MSM
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Westernized
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Westernization describes a population with incremental urbanization, profound lifestyle changes, including but not limited to, transition from autarchic means of producing food to controlled food production chain, increased hygiene and accessibility to modern medicals, introduction of food sterilization, increased exposure to pollutants, and switch from high-fiber simple diets to high-fat high-protein processes that has been undergoing for centuries.
- Group 0 sample size Number of subjects in the control (unexposed) group
- 93
- Group 1 sample size Number of subjects in the case (exposed) group
- 481
- Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
- 6 Months

Statistical Analysis
- Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).
- relative abundances
- Statistical test
- Mann-Whitney (Wilcoxon)
- Significance threshold p-value or FDR threshold used for differential abundance testing (if any)

Description: Differential abundance of Bacteroidaceae and Prevotellaceae families and Bacteroides and Segatella/Prevotella genera between MSM (n = 93), Westernized (n = 481), non-Westernized (n = 389), and urban Chinese (n= 66) samples (Wilcoxon rank-sum test with FDR correction).
Abundance in Group 1: increased abundance in Westernized
